serial: support for InstaShield IS-400 four port RS-232 PCI card.

From: Ignacio García Pérez

Description:
Adds support for the InstaShield IS-400 four port RS-232 PCI card.

---

The patch is pretty simple. No code, little more than just the PCI vendor/product id.

Thorougly tested and working.

Applies to kernels 2.6.22, 2.6.23, 2.6.24 and 2.6.25.
